算例：
|
||
1 正常发电工况：
|
||
- 均匀风
|
||
- 没有变桨、偏航、转速调整
|
||
对比结果
|
||
功率、叶片变形量、什么什么载荷？
|
||
|
||
q 叶片、塔架的振型如何看？
|
||
|
||
风速 8m/s
|
||
转速不知
|
||
|
||
1、Bladed、FAST 15MW模型直接对比结果
|
||
|
||
2、V0.5软件与fast 15mw对比
|
||
|
||
3、气动改用AeroDyn ED对比
|
||
|
||
|
||
V4.0 vs V3.5 新增
|
||
.fst
|
||
- seast
|
||
ElastoDyn
|
||
- 增加ptfmxyIner
|
||
- 增加YAW-FRICTION
|
||
|
||
AD 15
|
||
- 删去 AFAeroMod
|
||
- 删去 FrozenWake
|
||
- 增加NacelleDrag
|
||
- 增加BEM_Mod
|
||
|
||
潜在问题：
|
||
1 刚度、模态曲线是否一致
|
||
bladed 模态振型导出
|
||
bladed 模态与fast一致后，计算结果如何
|
||
2 气动结果差异
|
||
|
||
|
||
|
||
## 测试过程
|
||
|
||
- 采用v3.5气动数据情况下，多体计算结果与FAST一致
|
||
- 采用v4.0气动数据情况下，多体计算结果与FAST一致
|
